I'm working on a conlang (constructed language) and would like some input from the Less Wrong community. One of the goals is to investigate the old Sapir-Whorf hypothesis regarding language affecting cognition. Does anyone here have any ideas regarding linguistic mechanisms that would encourage more rational thinking, apart from those that are present in the oft-discussed conlangs e-prime, loglan, and its offshoot lojban? Or perhaps mechanisms that are used in one of those conlangs, but might be buried too deeply for a person such as myself, who only has superficial knowledge about them, to have recognized? Any input is welcomed, from other conlangs to crazy ideas.
You can't add extra features to the language without increasing the cognitive load in deciding when to use the extra features. You're still making everything else more difficult, it's just a distributed difficulty where everything is made more difficult by a miniscule amount, rather than one particular thing made difficult by a large amount.
I don't think that sentence would get added complexity. "adopted child" will likely be a 7-8 letter word using the same root as stepfather. Stepfather is a word that you can't derive from knowing "adoption" which make things harder for the language speaker. You can't derive spouse from knowing the word marriage.
